VC4106 Digital Insulation Resistance Tester Earth ground table

Description

Generalization
The instrument is a multifunctional earth resistance/earth resistivity tester equipped with a microcomputer.
The instrument employs digital signal settlement technology, which can draw earth measurement signals, possess features of high frequency, high accuracy and high resistance, and measure earth resistance/ earth resistivity accurately. The instrument can execute standard 3POLE and 4POLE earth resistance measurements and has 2POLE earth resistance measurement and earth resistivity calculation functions as well.
*The Instrument conforms to the following Safety Requirements:
IEC61010-1（CAT Ⅲ 600V,POLUTION degreeⅡ）
IEC61557-1、5（Electronic safety requirements for low voltage distribution system below AC 1000v and DC 1500v ）
*Basic Measurement Function
2/3/4- pole earth resistance measurement
Earth resistivity （ρ）calculation
*Earth Resistance Measurement employs AC simulation test,  4-kind of testing frequencies（94Hz、105Hz、111Hz、128Hz）,which are selectable by hand to reduce impacts from low interference sources.
*Auxiliary Earth Resistance Measurement Function
Testing and displaying auxiliary earth resistance.
*Warning Display Function for auxiliary earth resistance upper-limits
Displaying warnings for inaccurate measurements due to high auxiliary earth resistances
*Auto-range Function in Resistance Measurement and OL displays for over range.
*Indication Functions for high interference voltage.
*Measurement Function for series interference voltage.
*Backlight Function to view the test results in dimly areas.
*Setting Function to release the residual resistance (Rk) on the test leads.
*Setting Function for auxiliary earth spike interval under earth resistivity measurement, setting range: 1m～30m.
*Auto-power-off function and auto-backlight-off function with set time.
*Easy-for-operation data Store/Recall Function for independent measurement data (Max.100 groups)saving in the internal storage.
*Small and sturdy structure design, easy for operation, adaptable to spot transportation and bad environment.
